Question

這幾天我一直在尋找一個有效的解決方案，但它從來沒有奏效。

最小的可重現示例如下：

\documentclass[12pt,a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usepackage{csquotes}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage[authordate,autocite=inline,backend=biber,sorting=nyt,]{biblatex-chicago}
\addbibresource{Test.bib}
\usepackage[left=2cm,right=2cm,top=2cm,bottom=2cm]{geometry}
\DeclareUnicodeCharacter{202F}{\,}
\begin{document}

Test citing \citep{sanborn_learning_2014}

\printbibliography
\end{document} 

測試圍兜：

@article{sanborn_learning_2014,
    title = {Learning Democracy: Education and the Fall of Authoritarian Regimes},
    volume = {44},
    issn = {0007-1234, 1469-2112},
    url = {https://www.cambridge.org/core/product/identifier/S0007123413000082/type/journal_article},
    doi = {10.1017/S0007123413000082},
    shorttitle = {Learning Democracy},
    abstract = {Studies on what causes a state to democratize have focused on economic, social, and international factors. Many of them argue that higher levels of education should promote democracy. However, few articulate clearly how education affects democratization, and fewer still attempt to test the supposed link across time and space. This article fills that gap by considering how different levels of education influence democratization, and the conditions under which education is most likely to promote democracy. Analyses of eighty-five authoritarian spells from 1970 to 2008 find that higher levels of mass, primary, and tertiary education are robustly associated with democratization. Secondary analyses indicate that education is most effective in promoting democratization when both males and females are educated. An illustration from Tunisia follows.},
    pages = {773--797},
    number = {4},
    journaltitle = {British Journal of Political Science},
    shortjournal = {Brit. J. Polit. Sci.},
    author = {Sanborn, Howard and Thyne, Clayton L.},
    urldate = {2021-09-18},
    date = {2014-10},
    langid = {english},

我在 Linux、Texlive2019（安裝那個，而不是更新的）和 texmaker 上運行 Ubuntu 20.04。

有人有解決方案嗎？

Answer 1

兩個問題：

• 您的圍兜條目末尾的}丟失了

• \citep{}默認情況下 biblatex 不提供。 您可以改用\parencite{}或 biblatex 的natbib=true選項
